SUJET : Import survey in new device - Limesurvey

Hi,
I am a noob here. I downloaded limesurveynetworkstudy (network study) from the sample surveys available for download. I want to know how I can upload it on to my device. Do I need to extract the file or what procedure do I need to follow? I tried to read about it in FAQs and in the forum but was unable to find a suitable solution. Please help!
